Microvolt T-wave Alternans Not Covered

CMS reconsidered the NCD on microvolt t-wave alternans (MTWA) diagnostic testing and has determined not to extend coverage to the modified moving average (MMA) method because it is not deemed reasonable and necessary. The current policy remains in place providing for coverage of MTWA testing for the evaluation of patients at risk for sudden cardiac death only when the spectral analysis method is used. For complete details, read CMS Transmittal 88, CR6154, dated July 25, and NCD 20.30 on the CMS Web site.
